All the response is appreciated. We have 4 SS machines and 2 operators (normally). Some jobs take up to 15 minutes (multiple boards), some take less than 2 minutes (machine time). Some involve fixtures, preheat, some may require the operator to mon

Hi Bukas, thank you for taking the time to respond. My flow gauge shows 35 SCFH and the pressure is around 50 psi. Maybe the flow gauge is wrong? Thanks again. What delivery pressure do you run, if you run a selective solder machine? Thanks again. I

yeah I’ve tried to go down the road of internal recycling but the company carnt justify spending 20k on a machine that does it. Ah but where still onto it in other places though our SMT department has very minimal wastage on solder paste as we have b

Milara has released a inline stencil printer with jet printer in same machine - combi functionality. Not as fast in terms of jetting speed as mydata (uses Asymtek jet head) Can print only, jet only or both to say top up paste on certain areas after

It was a nitrogen delivery issue. I used a funnel (silicone) to direct the nitrogen to the board. The way the machine operates is, the nitrogen comes out about 7 cm away from the board, from a large opening around the nozzle. I cut a silicone funnel

Sam We install a lot of die in the SMT room using same process as SMT parts.Water soluble solder paste is used for attachment of die to ceramic and boards. Biggest problem i found is the adjustment from installing the die in the bonding area. The t

Using ERSA Ecoselect. I am curiuos to hear from other selective solder users as to what is the ideal lead lenght for your application on thru hole components. Shorter leads have helped us decrease solder bridges. We find ours to be from .75 mm to 1

not just speed, looking to reduce down time on having to re-do boards from bad stencil screening. also, the accuracy of placing solder paste down on PCB's. why would you want an employee spending so much time aligning fiducial marks from panel to pan

easier if you recycled on-site? You can still send off for reclaimation the oxide powder that your left at the end of the process. Failing that talk to your supplier to see if they have arrangements to do this for you or look at reducing dross - i f

Wow, you're very correct. I guess we use silicone to calibrate our machine, as follows: XPS spectral measurements of dimethyl silicone should include O(2s) at 25 eV, Si(2p) at 102 eV, Si(2s) at 153 eV, C(1s) at 285 eV, and O(1s) at 533 eV. The C(1s
